DC electrical properties investigations of xSb2O3(50-x) PbO:50V2O5(X=5, 10, 15 in molar ratio) glasses were carried out using X-ray diffractrometer (XRD), Scanning electron microscopy (SEM), differential scanning calorimetric analysis (DSC) and DC electrical conductivity with two probe techniques. XRD results shown that the Perfect vitrification has been achieved and DTA results have indicated that the substituent Sb2O3 is replacing PbO in the glass network in such a way that 1:1 composition and the eutectic nature is maintained. SEM investigations were carried out for the micro structural characterization of V2O5 crystal phases. The DC electrical conductivity studies on Sb2O3substituted glass systems annealed at 1400 C indicated that the conductivities increased as the concentration of dopant substitution increases
